JAMES GHAUNCEY DILDINE, OF CAMERON, MISSOURI.

BRIDGE-FLOOR.

To an whom it may concern:

Be it known that I, JAMES CHAUNOEY DILDINE, a citizen of the UnitedStates, residing at Cameron, in the county of Clinton and State ofMissouri, have invented certain new and useful Improvements inBridge-Floors, of which the following is a specification.

My invention relates to improvements in bridge-floors, and moreparticularly to a reinforced concrete block or slab for the same, andhas for one of its objects to provide a block or slab for use in forminga floor for old bridges, as well as new ones, that are too light tosustain or carry a continuous heavy concrete floor.

It further has for its object to form a concrete block or slab byproviding a skeleton of wire and filling the same inside and withoutwith concrete or other plastic material, thus forming a block or slabwith a continuous reinforcement near the surface thereof.

A. further object of my invention is to provide a slab designed to beplaced lengthwise of a bridge or other structure and to reach only fromone joist to the next nearest one, thus enabling it tolie flat on anystructure, irrespective of whether or not the same is level.

The invention consists in the several features and combination offeatures as more fully hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side view of a portion of abridge-floor, showing my invention applied thereto; Fig. 2, a side viewof one of the blocks or slabs; Fig. 3, an end view of a slab; Fig.4, aside view of a reel; Fig. 5, another view thereof; Fig. 6, an end viewof the reel; and Fig. 7, a side view of the skeleton, etc.

In the drawings, in which like numerals of reference indicatecorresponding parts throughout the several views, 1 represents theskeleton or framework reinforcement of the block or slab, and 2 theconcrete or other plastic material which fills and entirely covers thesame, forming the block or slab 3, and it will be readily understoodthat the reinforcement is situated or placed near the surfaces of thesaid blocks or slabs. The

Specification of Letters Patent.

skeleton 1 comprises diagonal or slanting crosswires 4 and longitudinalwires 5 braided therewith. I

In forming the skeleton 1 a reel 6 is employed, around which the wires 4are wound spirally, and then wires 5 are longituudinally woven on thesaid wires 4: in any suitable manner, after which the fabric made up ofthe wires t and 5 is removed from the reel and flattened out, as shownin Fig. 7, to form the skeleton for the block or slab.

Concrete slabs for bridges or other similar structures have never beensuccessful because bridges are not always built level, and the slabsbeing laid crosswise of the bridge, covering more than one joist, willnot lie fiat, whereas in my invention the slab is laid lengthwise of thebridge and reaches from only one joist to the next nearest one, thusforming a perfectly flat floor.

I do not wish to be limited to the exact details of construction andarrangement of parts as hereinabove set out, as the same may be variedto meet the requirements of use without departing from the spirit andscope of my invention.

I therefore reserve the right to all varia-' ing the same intorectangular shape, and

then filling and covering the said skeleton withconcrete or otherplastic material, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.
